The import and export of a template takes place on a template’s settings page. These can be found under the filter’s settings in the site administration->plugins->filters->[filtername] area.

The template file you download from here is a ZIP file (.zip) and you must first expand it to get the template file (.txt) that you use to import.

Importing a template

On each template settings page on the top right, there is a green box with the word “bundle” inside it. To restore a template from a file, you need to drag the .txt file over the green bundle button of a template settings page. The border of the button will turn blue.  If you then “drop” the text file, it will fill in all the fields of the settings page. You need to save the settings page after that.
